Crypto.Cipher.RC4
Description
Simple implementation of the RC4 stream cipher. http://en.wikipedia.org/wiki/RC4
Initial FFI implementation by Peter White peter@janrain.com
Reorganized and simplified to have an opaque context.

Arguments
| :: ByteArrayAccess key | |
| => key |
The key |
| -> State |
The RC4 context with the key mixed in |
RC4 context initialization.
seed the context with an initial key. the key size need to be adequate otherwise security takes a hit.
Arguments
| :: ByteArray ba | |
| => State |
rc4 context |
| -> ba |
input |
| -> ( State , ba) |
new rc4 context, and the output |
RC4 xor combination of the rc4 stream with an input
generate :: ByteArray ba => State -> Int -> ( State , ba) Source #
generate the next len bytes of the rc4 stream without combining it to anything.
